William Herbert's "New Directory for the East Indies" was encouraged by the East India Company and first published in 1758. It quickly became the de-facto atlas of the region taking over prime place from the Third Part of the English Pilot which by then was over 50 years old. Further editions appeared in 1759, 1767 and 1776. It is in this latter edition that numerous new charts were included, many based on the highly talented Alexander Dalrymple who worked for the East India Company from 1752 and became its first Hydrographer in 1779.
